--user-data-dir=DIR
              Specifies the directory that user data (your "profile") is kept  in.   Defaults  to
              ~/.config/chromium  .   Separate  instances of Chromium must use separate user data
              directories; repeated  invocations  of  chromium-browser  will  reuse  an  existing
              process for a given user data directory.
